784159 divided by 78 
Our goal is to divide 784159 by 78.

Advancing to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 78

Moving on to step 2:
The number 78 fits into 78 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 78 away from 78, we end up with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 78

On to step 3:
If we divide 4 by 78, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 78

Moving on to step 4:
41 divided by 78 is 0 with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtracting 0 from 41 leaves us with 41.
Fetch the next digit (5) from the dividend, attach it to 41 and continue: 415 / 78

On to step 5:
The number 78 fits into 415 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1005.0
Subtracting 390 from 415 leaves us with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 78

Let's proceed to step 6:
If we divide 259 by 78, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 10053.0
Subtract 234 from 259 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
78 goes into 250 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 10053.3
If we subtract 234 from 250, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
78 goes into 160 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10053.32
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 78 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10053.32
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 78 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10053.3205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 78 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 10053.32051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
When dividing 220 by 78, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 10053.320512
If we subtract 156 from 220, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
78 goes into 640 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 10053.3205128
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
78 goes into 160 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 10053.32051282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 10053.32051282, and the remainder is 4e-09.
